#162386 - CJNE? Responding to: ???'s previous message |
One of the instructions is
CJNE A, direct, rel If one value is in A, and the other in a register, which is directly addressable, e.g. B, then that instruction will do it. If you have to, you may move data around to make this possible, for example, put one value in A and the other in B, then use CJNE A, B, <relative destination>. The "bible" (I don't know why there isn't a readily accessible link to it at the left of this page) will tell you how this instruction works. You may find its effect on the carry bit of interest.
